TELESCOPIC POLE.

T '0 all whom it may concern Be it known that 1, 12mm 0. looxn, acitizen of' the United States, residing at Lake City, in the county ofWabash-a and State of Minnesota, have invented certain new and usefulimprovements in Telescopic Poles, of which the following is aspecification, reference being had therein to the accompanying drawing.

,This invention rovides poles that are formed of telescopic sections,whereby the sections may be nested one within another and made intocompact units. The poles particularly. are adapted for use astentsupports, they may be stowed easily in a canoe, automobile, or othervehicle, and the invention contemplates both upright and ridge poles ofthis kind.

The arrangement of each pole is such that it may be easily; and quicklyextended and telescoped means are provided for reliably maintaining, thepoles extended, and the arrangement is such that the ridge-pole may beconnected to the upright poles.

When read in connection with the description herein, the details ofconstruction and arrangement of parts contemplated by the invention willbe apparent from the accompanying drawing, forming part hereof, whereinembodiments of the invention are disclosed, for purposes ofillustration.

While the embodiments herein explained now are considered to bepreferable ones, it is to be understood that'alterations can be made inthem within the limits of the claims without departing from the natureand spirit of the invention.

Like reference-characters refer to corresponding parts in the views ofthe draw ing', of which Figure 1 is a view of an upright pole extended;Fig. 2 is a View, partly in section,

of an upright pole telescoped; Fig. 3 is a View of a ridge-poleextended; Fig. 4.- is a view, partly in section, of a ridge-poletelescoped; Fig. 5 is an enlarged sectional View of a joint; Fig. 6 is atransverse sectional view, on the line 66, Fig. 2; and Fig. 7 is a topview of the cap and base plate at the bottom of the upright pole.

The poles are made preferably of metal tubi g of difierent sizes in thevarious sectio s, whereby the sections may telescope one with another. Y

vent the pole from settling into the ground when in usea The uprightpole includes any desired number of upper sections 11, each suflicientlysmall to slide within the next lower section. The upper end of eachsection is exteriorly screw threaded, as shown at 1'2, and each of thesethreaded portions, except that of the upper section, is engaged by aninteriorly threaded end of a collar 13-. The bore of each collar, exceptin its threaded portion, is of less diameter than the section to whichit is secured, whereby there is an abutment 1% at the end of thethreaded portion of the bore. The section telescoping into anothersection to which a coll aris attached is of a size to contact snuglywith the smaller portion of the bore of the collar. Each section, exceptthe lower one, has on its lower end an exterior annular flange orshoulder 1:), which snugly contacts with the inner surface of thesection in which it is disposed and which is arranged to seat againstthe abutment 1 1 of itscontaining section when the sections are extendedand thereby to prevent separation of thesections. Each of the sectionsprovided with a flange 15 has on its exterior a screw-threaded portion16 so spaced from'the flange that it will have position just outside ofthe outer end of the collar 13 when the sections are extended. On eachof the sections formed with a threaded portion 16 there is a nut 17arranged to screw on those portions and against the end of the collarof'the containing section, whereby flange 15 can be drawn tightlyagainst the abutment 14; and the sections held firmly extended. The nuton one section is sutliciently large to prevent the nut on the nextlarger section from passing over it, whereby disarrangement of the nutson the pole is obviated. A cap 18 is secured on the upper or outer endof the upper sec tion, and this cap is sufficiently large to prevent thesection containing the upper section and the nut thereon from passingover it. The cap 18 has a pin 20 or the like exextended condition. Theflanges and abutments serve to prevent the sections from becomingentirely separated when they are beingl drawn outwardly of one another.If it is esired entirely to disassemble the parts of the pole, that maybe accomplished by removing the caps and collars described.

The ridge-pole may have any desired number of sections, and it isconstructed in substantially the same manner as the upright pole, exceptthat the middle section 21 is the largest, it is about twice the lengthof the outer-sections 22, it is arranged to have outer sectionstelescope therein from each end, and it has at each end a collar 13 forthe same purpose as'the collars of the upright 'pole. Midway between itsends, the middle sect-ion has a stop 23' to prevent the outersections-from passing too far into it from one end and pushing sectionsout from the other end. The outer sections are formed, as are the upper.sections of the upright pole, with collars 13, abutments 14,- fiangesl5, threaded portions 16, and nuts 17, and the end sections have attheir outer ends the caps 18. The middle section of the ridgepole beingthe largest of the sections thereof, the pole when extended is strongestin the middle portion Where the greatest strain is imposed when in use.A hole 24 is provided near the outer end of each outer section of theridge-pole to receive the pin on the upper end of an upright pole andthereby to form a reliable connection therewith when two upright polesare used, one at each end of the ridge-pole, to support the latter. Incase it is desired to use only one uprightpole, and that at the centerof the Copies of this patent may be obtained for Letters Patent, is

1. A pole comprising a larger section, a smaller section telescopic inthe larger, an abutment in the larger section near its end, a shoulderon the smaller section capable of contact with said abutment when thesmaller section is extended, screw-threads on the smaller section havingposition exterior of a an end of the larger section when thesections areextended, and a nut coiiperable with said threads and the end of thelarger section to cause said shoulder and abutment to contact and tomaintain the sections in.

extended relation.

2. A pole comprising'tubular'sections of different sizes one telescopicwithin the other, a collar screwed onto the end of the larger sectionthrough which the smaller section slides and on said collar an interiorabutment, a shoulder near the inner end of the inner section capable ofcontact with said abutment when the sections are ex tended andscrew-threads onthe smaller section having position exterior of saidcollar when the sections are extended, and a nut cooperable with saidscrew-threads and the outer end of said collar to cause said shoulderand abutment to contact and to. maintain the sections in extendedrelation.
